samples of your components to us and we will process these to achieve the finish you require.
For professional and friendly advice, call Customer Service now.
We also supply a 4-page Blast Media Guide, covering topics such as materials used for media, how media type affects finish, and how to select the right media. Download the Blast Media Guide here, or ask Customer Service for a printed copy.

if your equipment is older. Spare parts lists covering all the common parts on both blast and wash
machines are available from Customer Service.

How much compressed air do I need to run my blast machine?
A.
To answer this, we will need to know the type of blast system you have -
i.e. is it suction feed or pressure feed? Once this is known, the air consumption will further depend upon
the bore of the air control jet (suction feed) or the bore of the nozzle (pressure feed) and also the blast
pressure you are using.
What’s the difference between suction feed and pressure feed blasting?
A.
A suction feed system uses a venturi siphoning action to draw the blast media from a hopper into the compressed air stream within the gun nozzle itself. The air and media pass through the nozzle, to be directed at the component.
A pressure feed system stores the blast media within a pressure pot. When the pot is sealed, the blast media falls through a valve into a compressed air stream within the blast hose. It is then accelerated through the blast nozzle to impact upon the component.
The pressure feed system produces faster moving blast media and offers cycle times that can be up to 4 times faster than a suction feed system.
Both methods can use a very wide selection of blast media. By additionally varying the
media particle size and the blast pressure used, these two systems can offer a range of finishing from light,
delicate work to high production, demanding and aggressive applications.
My blast machine seems very slow - can I speed it up in some way?
A.
As a general rule, the greater the flow of compressed air, the faster the blasting process becomes.
If you have a suction feed machine, you can maybe consider a larger air control jet or even a bigger gun. If you have a pressure feed machine, perhaps a larger nozzle could help.
Please call Customer Service for further assistance.
